Bought it. Love it so far. It's an excellent test of your jump n' shoot skills with a match three twist. As you play more you unlock more levels/characters/enemies. Each character has different mechanics so you have a double jumper, a character who can float a little bit by holding jump, etc. Since you can't attack enemies directly (You have to destroy a block that's touching them) it adds just enough thought to help the game avoid being braindead, but not so much that in distracts you from the jumping n' shooting.
